Leak Testing Equipment and End-of-Line Functional Test Machines
For sealed, pressurised or fluid-carrying parts, leak testing is the final guarantee of quality. SCreate designs and builds leak testing equipment and end-of-line (EOL) functional test machines tailored to your part and acceptance criteria. We apply pressure decay, differential (mass flow) and helium tracer-gas methods to detect leaks down to the required sensitivity, with automatic sealing fixtures, calibrated instruments and clear PASS/FAIL judgement. Stations can be standalone, semi-automatic or fully integrated into an assembly line with traceability. We combine this with functional tests — flow, pressure, electrical and performance verification — for complete end-of-line quality gating.
Capabilities
What We Deliver
Pressure Decay Leak Testing
Charges the part to a set pressure and monitors decay over time — the most common, cost-effective method for sealed housings and assemblies.
Differential Pressure Testing
Compares the test part against a reference master for higher sensitivity and faster cycle times on tight-leak applications.
Helium / Tracer-Gas Leak Detection
Mass-spectrometer helium testing for the highest sensitivity, used on hydrogen fittings, fuel cell and HVAC components.
Automatic Sealing Fixtures
Precision CNC-machined sealing fixtures and pneumatic clamping for repeatable, fast and operator-independent sealing of test ports.
EOL Functional Testing
End-of-line stations for flow, pressure, electrical continuity, torque and performance verification with automatic data recording.
Traceability & Data
Per-part result logging, barcode association, PASS/FAIL marking and MES/SPC data output for full quality traceability.

FAQ
Frequently Asked Questions
What is leak testing equipment used for?
Leak testing equipment verifies that sealed, pressurised or fluid-carrying parts — battery trays, valve bodies, fittings, cooling plates, housings — meet their air-tightness specification before shipment, replacing unreliable water-bath methods.
Which leak test method should I use?
Pressure decay suits most sealed assemblies; differential pressure gives higher sensitivity and shorter cycles; helium tracer-gas is used when very small leak rates must be detected, such as hydrogen and fuel cell components. We recommend a method based on your leak-rate spec and cycle time.
Can the leak tester be integrated into an assembly line?
Yes. We build standalone, semi-automatic and fully inline leak test stations with automatic loading, sealing, testing and reject sorting, plus data output to your MES.
Do you also provide functional (EOL) testing?
Yes. We combine leak testing with end-of-line functional tests — flow, pressure, electrical and performance verification — in a single station or sequential line for complete quality gating.
